摘要

Purpose

This study aims to investigate the vibration characteristics and mechanical performance of hybrid polymer composites reinforced with jute (J), glass (G), stainless steel-304 (S), and aluminum (Al) wire mesh, with a focus on potential applications in vibration-sensitive automotive structures.

Methodology

Four symmetric hybrid laminates J/S/J/S/J, G/G/S/G/G/S/G/G, G/S/J/J/S/G, and J/Al/J/Al/J along with their virgin counterparts, were fabricated using the hand layup process followed by compression molding. Experimental modal analysis was carried out under free–fix, fix–fix, and free–free boundary conditions using a Fast Fourier Transform (FFT) analyzer. Flexural testing was performed according to ASTM D790, and moisture absorption behavior was also studied. A numerical model was developed to validate the bending modal frequencies.

Results

The J/S/J/S/J laminate exhibited superior damping performance under all boundary conditions among the hybrid laminates. Additionally, it showed a 105% increase in flexural strength and a 249% improvement in modulus compared to the virgin jute laminate. Moisture absorption improved damping but lowered natural frequencies, while analytical and numerical predictions closely matched experimental results.

Conclusion

The results demonstrate that strategic hybridization using jute, glass fibers, and metal wire meshes can significantly improve both mechanical and vibration properties of polymer composites. These tailored laminates offer strong potential for lightweight, vibration-critical applications, especially in automotive and structural components.
